Thomas Sowell‘s latest column at Human Events questions socialism’s appeal.

Socialism sounds great. It has always sounded great. And it will probably always continue to sound great. It is only when you go beyond rhetoric, and start looking at hard facts, that socialism turns out to be a big disappointment, if not a disaster.

While throngs of young people are cheering loudly for avowed socialist Bernie Sanders, socialism has turned oil-rich Venezuela into a place where there are shortages of everything from toilet paper to beer, where electricity keeps shutting down, and where there are long lines of people hoping to get food, people complaining that they cannot feed their families.

With national income going down, and prices going up under triple-digit inflation in Venezuela, these complaints are by no means frivolous. But it is doubtful if the young people cheering for Bernie Sanders have even heard of such things, whether in Venezuela or in other countries around the world that have turned their economies over to politicians and bureaucrats to run.

The anti-capitalist policies in Venezuela have worked so well that the number of companies in Venezuela is now a fraction of what it once was. That should certainly reduce capitalist “exploitation,” shouldn’t it?

But people who attribute income inequality to capitalists exploiting workers, as Karl Marx claimed, never seem to get around to testing that belief against facts — such as the fact that none of the Marxist regimes around the world has ever had as high a standard of living for working people as there is in many capitalist countries.

Facts are seldom allowed to contaminate the beautiful vision of the left. What matters to the true believers are the ringing slogans, endlessly repeated.

When Senator Sanders cries, “The system is rigged!” no one asks, “Just what specifically does that mean?” or “What facts do you have to back that up?”

In 2015, the 400 richest people in the world had net losses of $19 billion. If they had rigged the system, surely they could have rigged it better than that.

But the very idea of subjecting their pet notions to the test of hard facts will probably not even occur to those who are cheering for socialism and for other bright ideas of the political left.
